Biography
William Hemsley Emory was born in Queen Anne's County, Maryland in 1811, and he graduated from West Point in 1831. He served in the US Army Corps of Engineers and as a surveyor, becoming the map-making authority of the trans-Mississippi American West. During the Mexican-American War, he accompanied Stephen W. Kearny during his capture of New Mexico and California, and, after the war, he mapped the new Texas-Mexico border and the Gadsden Purchase border in 1853. In 1862, he became a brigade commander for the Union Army of the Potomac, and he was later transferred to the West as a Brigadier-General, commanding a division at the Battle of Port Hudson and commanding a corps in the Valley Campaigns of 1864. After the war, he served as Department of the Gulf, supervising Reconstruction in Louisiana, Arkansas, and Mississippi, and he negotiated peace with the New Orleans White League in 1874. For political reasons, General Philip Sheridan had Emory retire in 1876, and he died in Washington DC in 1887.
